Launching a startup is exciting, but it’s also overwhelming. You’ve got a brilliant idea, you’re building your product, and you’re hustling to get your first customers. The challenge? None of it matters if people can’t find you online. That’s where SEO comes in.
Search engine optimization is no longer a “nice-to-have.” For a startup, it’s truly the difference between being invisible and being discovered by the right audience. The catch? SEO is complex, time-consuming, and constantly changing.
